- lo all whmn it may concern.-

Be it known that I, OHAuNcEY W. GAY, a

- citizen oflthe United States of America, and a resident of West Springfield, in the county of Hampden and State of Massachusetts, havein vented certain new and useful Improvements in Machines for Surface-Finishing Paper, of which the following is a full, clear, and exact description. v

This'invention relates to improvements in a machine for imparting to blanks of paper a surface finish resembling in aspect the surface of textile fabric. I

The Object of the inventionis to devise a machine for the stated purpose which is of extremely simple and inexpensive construction, strong and durable, and susceptible of adaptation to vary the character of the surface finishto be imparted to the paper.

The invention includes in combination a pair of peripherally-adjacent cylinders, one of which essentially has, but both of which preferably have, covering of cloth peripher- T surfacing action of said rolls.

The invention furthermore consistsin certain combinations and arrangements of parts and the constructions of parts, all substantially as hereinafter fully described, and set forth in the claims.

In the drawings, Figure 1 is in substance a side elevation of the machine as seen next inside of one of the side'm'embers of the supporting-frame that is understood to be omitted. Fig. 2 is a perspective and sectional 'view, on a larger scale, of a portion of one of the cylinders of the machine for particularly illustrating features of construction hereinafter referred to. Fig. 3 is a sectional View in detail to show a construction at one end supporting-legs A and having mounted therein axially transversely the cylinders B and 0, having end journals and arranged to run peripherally in contact orin peripheral proximity, strong and immovable journal-bearings a a being provided, so that any tendency of the cylinders to separate will be ably resisted. Both of the cylinders are shown as having peripherally in tension therearound a layer Z) of textile fabric, the ends of which are approached, but do not meet, being carried within a gap or recess d in each roll and secured.

While the invention is not necessarily limited to any particular manner of securing the layer of textile fabric peripherally around on each cylinder, a practical, desirable, and tested expedient is here illustrated as consisting in a carrier-strip f of flexible'material, which may be strong heavy paper, leather, rubbercovered cloth, or watch-spring metal, the ends thereof having connection and winding engagement with rods g, located within the aforementioned gaps d, extending in parallelism with the axis of the cylinders and having bearings through the portions of or equipments for the cylinders, which are represented at it, constitute walls at the ends of the recesses, which are as one with the body of the cylinder. The outer ends of the said rods 9 have screw-d riven slots g or equivalent formations, whereby they may be turned, and setscrews 9 are extended radially through the portions 7a, forming the end Walls to the recesses to confining engagements against the sides of the said rods.

The cloth 6 is secured in any suitable manner on the outer surface of the carrier-strip f, as may be done by gluing it at its end portions or throughout its entire area or by mechanical fastenings within the recesses.

By loosening the confining-screws g and turning the rods g, one or both, the carrierstrip and cloth strip thereon may be tensioned around the cylinder in the required degree.

E represents a feed table on which the blanks w may be piled, the. upper surface of Such table being at a plane adjacent the one which is coincident with the under side of the cylinder B, and between the inner edge of the feed-table and the under peripheral portion .of the cylinder is a periodically-movable gage consists of a plate having an upturned extremity i and is mounted on a rocking support 7', having radial arms to which a weight f is hung, so that normally the carrier will be swung to present the upturned extremity i of the gage device against the under side of the cylinder, as represented by the dotted lines in Fig. 1. The carrier 1' has, however, a leverarm extension it, understood as located in a plane beyond but adjacent one end of the cylinder, such arm extending across the orbital path of a stud k on the end of the cylinder, so that once in every revolution of the cylinder the said stud Will impinge against the lever-arm 7a and cause the gage z' i to resemble the position represented in the full lines in Fig. 1.

The cylinders have spur gear-Wheels m m at their ends meshing into each other, and one of the cylinder gear-Wheels is driven by a pinion gear-wheel m on a counter-shaft 02, for which a driving-pulley n is provided. The rotations of the cylinders are as represented by the carriers, Fig. 1.

Gr G represent gripper devices having their locations in the recesses (Z in both cylinders, the one G gripping the leading end of the blank brought into juxtaposition and properly limited by the gage aforementioned and carrying the blank around with its surface against the surface of cylinder B until the recessed part of cylinder C comes opposite the corresponding recesses of cylinder B, whereupon the grippers G release the leading end of the blank at a location in a line perpendicular to and extending between the axes of both cylinders, and the gripper Gr engages the blank and carries it around over the upper half of cylinder C, the whole surface, with the exception of the small leading portion which is gripped, being subjected to the pressure-contact and surface-finishing action of the textile-covered pair of cylinders, and when the blank has been carried so that its leading end is descending the left-hand upper portion of the cylinder C the gripper G releases it, and it is fed onto the receiver or delivery-support therefor.

The gripper devices for both cylinders are substantially alike and the actuating means therefor also; butthe gripper-operating means are reversely arranged, so that when the gripper for cylinder B is open to release the leading end of the blank the gripper for the cylinder C closes to then engage the blank.

The grippers are carried on rock-shafts 0, journaled in the opposite end walls It of the recesses (Z, said rock-shafts ranging along in said recesses, sunk below the periphery of the cylinders, and each rock-shaft has at its end a lever extension 19, carrying a frictionroller p arranged to impinge against the cam-plate r at the end of the frame and adjacent the end of the cylinder, 8 8 representing supporting-studs extending from the inner side of the frame toward the end of the cylinder, and on which studs the cam-plates are secured.

The springs 2f, having each one end attached to a stud t at the end of the cylinder and its other end attached to the lever extension 7) of the rock-shaft 0, is operative to normally hold the gripper closed, the cam-plate when the roller on the lever 12 is bodily brought into impingement therewith opening the gripper and holding it open until such roller has in its revoluble movement with the cylinder passed outof engagement with the cam-plate, whereupon the gripper is by the reaction of the spring swung from its open position, represented by dotted lines at the remote portion of Fig. 1, to the closed position, there represented by full lines.

It is noticed that the cams w 1' lntvereverse arrangements relatively to the respccti ve gripper-provided cylinders for a corresponding reversing operation of the grip 'iers.

To receive the paper after it has passed through the cylinders, there is provided a table F, having a guide f mounted thereon, which is carried by the frame A adjacent the cylinder C, there being arranged a brush I near the upper end of the guide adapted to contact with the cylinder A.

The layer of cloth which constitutes the upper surface of each cylinder may be common cotton or linen cloth, and the so-surfaced portions of both cylinders in coming together as the cylinders rotate impress the textilelike cylinder-surfacing into the paper which is carried between the cylinders, so that it is delivered from the machine with both sides having cloth-like surfaces.

By having the extremities of the surfacingcloth located within the recesses (l (l of the cylinders and having the cylinders arranged to run conjointly in the manner described no seam-mark will be produced or left upon any portion of the blanks subjected to the clothsurfacing action.

Substantially the present improvements in machines for surface-finishing paper have been described but not claimed in an application for Letters Patent of the United States filed byme April 27, 1903, Serial No. 74
